Titanium.Media.AudioPlayer
Extends Titanium.Proxy
An audio player object used for streaming audio to the device, and low-level control of the audio playback.
On Android, when you are done playing a given audio file, you must call the release method to stop buffering audio data and release associated system resources. Since 7.5.0, this method is available on iOS as well and will release all audio-player related resources. After this method has been called, the object should not be accessed anymore.
On iOS, you can control how the audio stream interacts with other system sounds by setting Titanium.Media.audioSessionCategory. Since Titanium 7.5.0, this API uses the AVPlayer API for a more modern and performant audio playback.
Use the Titanium.Media.createAudioPlayer method to create an audio player.
Examples
Audio Streaming
The following example demonstrates using the AudioPlayer object to stream audio.
var win = Ti.UI.createWindow({
title: 'Audio Test',
backgroundColor: '#fff',
layout: 'vertical'
});
var startStopButton = Ti.UI.createButton({
title: 'Start/Stop Streaming',
top: 10,
width: 200,
height: 40
});
var pauseResumeButton = Ti.UI.createButton({
title: 'Pause/Resume Streaming',
top: 10,
width: 200,
height: 40,
enabled: false
});
win.add(startStopButton);
win.add(pauseResumeButton);
// allowBackground: true on Android allows the
// player to keep playing when the app is in the
// background.
var audioPlayer = Ti.Media.createAudioPlayer({
url: 'www.example.com/podcast.mp3',
allowBackground: true
});
startStopButton.addEventListener('click', function() {
// When paused, playing returns false.
// If both are false, playback is stopped.
if (audioPlayer.playing || audioPlayer.paused) {
audioPlayer.stop();
pauseResumeButton.enabled = false;
audioPlayer.release();
} else {
audioPlayer.start();
pauseResumeButton.enabled = true;
}
});
pauseResumeButton.addEventListener('click', function() {
if (audioPlayer.paused) {
audioPlayer.start();
} else {
audioPlayer.pause();
}
});
audioPlayer.addEventListener('progress', function(e) {
Ti.API.info('Time Played: ' + Math.round(e.progress) + ' milliseconds');
});
audioPlayer.addEventListener('change', function(e) {
Ti.API.info('State: ' + e.description + ' (' + e.state + ')');
});
win.addEventListener('close', function() {
audioPlayer.stop();
audioPlayer.release();
});
win.open();
Properties 38
Boolean to indicate if audio should continue playing even if the associated Android Activity is paused.
Setting allowBackground to true allows the audio to continue playing, for
example, if the application is in the background.
Default: false
Indicates whether the player allows switching to "external playback" mode.
Default: true
Inherited from Titanium.Proxy
The name of the API that this proxy corresponds to.
Used to identify the volume of audio streams for alarms.
Used to identify the volume of audio streams for media playback.
Used to identify the volume of audio streams for notifications.
Used to identify the volume of audio streams for the phone ring.
Used to identify the volume of audio streams for DTMF tones or beeps.
Used to identify the volume of audio streams for voice calls.
Focuses on the current audio player and stops other audio playing.
If true then all other audio sources will be stopped when Titanium.AudioPlayer is started or resumed.
Default: false
Returns the audio session id.
Changes the audio-stream-type.
Default: <Titanium.Media.AudioPlayer.AUDIO_TYPE_MEDIA>
Bit rate of the current playback stream.
Inherited from Titanium.Proxy
Indicates if the proxy will bubble an event to its parent.
Default: true
Size of the buffer used for streaming, in milliseconds.
Prior to Titanium 7.5.0, this property was set in bytes. Since the internal iOS API moved to the more modern AVPlayer, this property now works with milliseconds instead.
Estimated duration in milliseconds of the file being played.
May return 0 when playing a live stream.
Indicates whether the player is currently playing video in "external playback" mode.
Boolean indicating if the player is idle.
true if the player is in the initialized state: that is, not playing, paused,
or waiting for data.
Inherited from Titanium.Proxy
The Window or TabGroup whose Activity lifecycle should be triggered on the proxy.
Indicates whether or not audio output of the player is muted.
Only affects audio muting for the player instance and not for the device.
paused
BooleanBoolean indicating if audio playback is paused.
Boolean indicating if audio is currently playing.
Returns false if playback is stopped or paused.
Current playback progress, in milliseconds.
Returns zero if bitRate has not yet been detected.
Indicates the desired rate of playback; 0.0 means "paused", 1.0 indicates a desire to play at the natural rate of the current item. In addition, 2.0 would mean that the audio plays twice as fast.
Setting the value of rate to 0.0 pauses playback, causing the value of
the state property change to Titanium.Media.AUDIO_STATE_PAUSED.
Setting the rate to a non-zero value causes the value of the state property
to become either <Titanium.Media.AUDIO_STATE_WAITING_FOR_QUEUE> or
Titanium.Media.AUDIO_STATE_PLAYING, depending on whether sufficient
media data has been buffered for playback to occur and whether the player's
default behavior of waiting in order to minimize stalling is permitted.
Default: 0
Current state of playback, specified using one of the STATE constants defined on this object.
Deprecated since 7.5.0
Use Titanium.Media.AUDIO_STATE_BUFFERING instead.
Audio data is being buffered from the network.
Deprecated since 7.5.0

Deprecated since 7.5.0
Use Titanium.Media.AUDIO_STATE_WAITING_FOR_QUEUE instead.
Player is waiting for audio data to fill the queue.
Current playback position of the audio.
Time is reported in milliseconds.
url
StringURL for the audio stream.
Volume of the audio, from 0.0 (muted) to 1.0 (loudest).
This setting controls the volume of the sound relative to the overall volume setting for the device.
On iOS, to adjust the volume of the device, set the volume property of
Titanium.Media.appMusicPlayer and set the Titanium.Media.audioSessionCategory property
to either Titanium.Media.AUDIO_SESSION_CATEGORY_AMBIENT,
Titanium.Media.AUDIO_SESSION_CATEGORY_SOLO_AMBIENT,
or Titanium.Media.AUDIO_SESSION_CATEGORY_PLAYBACK.
Boolean indicating if the playback is waiting for audio data from the network.
This property is true if the player is in any of the waiting states, including
buffering, starting, waiting for data, and waiting for queue.

Pauses audio playback.
On iOS, the pause call operates as a toggle. If the stream is already paused,
calling pause again resumes playing the stream.
On Android, the pause call does nothing if the stream is already paused.
On both platforms, calling Titanium.Media.AudioPlayer.start on a paused stream resumes play.
Deprecated since 7.5.0
Use the cross-platform API Titanium.Media.AudioPlayer.start instead.
Starts or resumes audio playback.
This method is identical to .
release
since Android 0.9, iPhone 7.5.0, iPad 7.5.0Stops buffering audio data and releases audio resources.
On Android, this method should be called when you are done streaming a given audio object, to release underlying resources, including buffered data.
On iOS, this method can be called for parity to release the current player
instance and it's observers. Note: If you are listening to the progress event,
you should remove and re-add the event listener.
Inherited from Titanium.Proxy
Removes the specified callback as an event listener for the named event.
| Parameters | Type | Description |
|---|---|---|
| name | String | Name of the event. |
| callback | Callback<Titanium.Event> | Callback function to remove. Must be the same function passed to 4 fields
|
restart

Moves the playback cursor and invokes the specified block when the seek operation has either been completed or been interrupted.
Use this method to seek to a specified time for the current player item and
to be notified by the seek event when the seek operation is complete.
| Parameters | Type | Description |
|---|---|---|
| time | Number | The time in milliseconds to seek to. |
Deprecated since 7.5.0, removed in 10.0.0
Use the cross-platform API Titanium.Media.AudioPlayer.pause instead.
Sets the value of the paused property.
On iOS, this method can be used to pause and unpause playback. For portability, it is preferable to use the Titanium.Media.AudioPlayer.pause and Titanium.Media.AudioPlayer.start methods instead.
